ABSTRACT
The HD ground was broken with cameras, in the main, using three 2/3-inch chips with each chip dedicated to a single color, either Red, Green or Blue, and each chip was sent only the part of the image that contained that color. This was achieved by using 3 bits of glass, two in the form roughly of a prism, to separate the colors for this was, and is in this configuration, essential because the pixels on each chip are only sensitive to brightness, not color. To date no one has devised a pixel that, independently, can discern color. I have to wonder at the fact that the human eye can do this using the cones in the retina, but even in this wondrous device, the human eye, brightness is independently assessed by the rods.
